Unit 2 What a day!
重难点详解
1.不规则变化的动词过去式
Su Hai, Mike, Liu Tao and I went to the park by bike.我和苏海、迈克、刘涛骑自行车去了公园。
英语中有许多动词的过去式变化是不规则的,需要同学们单独去记忆。但如果能在学习中经常整理和总结,我们也能得到如下一些记忆不规则动词过去式的经验:
(1)单词原形与过去式完全相同的。如:
let-let; put-put; cut-cut; fit-fit; hurt-hurt; read-read
(2)把单词中i, o, y变为a。如:
sit-sat; swim- swam; come-came; become-became; run-ran; sing-sang
(3)把单词中的i变为o的。如:
write-wrote; ride-rode; drive-drove; win-won
(4)把词尾的-eep变为-ept的。如:
Sweep-swept; keep-kept; sleep-slept
(5)把词尾的-ow, aw变为-ew的。如:
draw-drew; know-knew; grow-grew; blow-blew
(6)有些动词的过去式以-aught或-ought结尾。如:
buy-bought; bring-brought; teach-taught; catch-caught; think-thought
(7)把词尾的-end变为-ent的。如:
send-sent; spend-spent; lend-lent
(8)把词尾的-ay变为-aid的。如:
say-said; lay-laid; pay-paid
(9) 单词原形与过去式完全不同的。如:
go-went; am/is-was; are-were; have-had; eat-ate; make-made; see-saw; take-took; do-did
【例题】单项选择。
( )1.Last year I always to Julian’s house for lunch.
A.go B.went C.goes
( )2.I ran out and the cat back in again.
A.bringing B.bring C.brought
【答案】1.B 2.C
2.关于天气的表达
Then, the weather became windy and cloudy.然后,天气变得有风且多云。
表示天气的形容词,一般由“其对应的名词+y(或双写最后的辅音字母再加y)”变化而来。例如:
名词
形容词
sun太阳
sunny晴朗的
wind风
windy有风的
cloud云
cloudy多云的
rain雨
rainy多雨的
3.What happened, Bobby?出什么事了?
询问某人发生了什么事情的句型结构为“What happened(+to+某人/某物)?”, happened是happen的过去式,意为“发生”。询问某人/某物怎么了的句型结构为“What’s the matter with+某人/某物?”。
【例题】根据中文提示,完成下列对话。
——出什么事了山姆?——我在森林里迷路了。
—What , Sam?
—I my way in the forest.
【答案】happened; lost
